Html¶

Creating Charset Tags¶

Cake\View\Helper\HtmlHelper::charset($charset=null)¶

Used to create a meta tag specifying the document’s character. The default value is UTF-8. An example use:

echo $this->Html->charset();

Will output:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

Alternatively,

echo $this->Html->charset('ISO-8859-1');

Will output:

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />

Linking to CSS Files¶

Cake\View\Helper\HtmlHelper::css(mixed $path, array $options = [])¶

Creates a link(s) to a CSS style-sheet. If the block option is set to true, the link tags are added to the css block which you can print inside the head tag of the document.

You can use the block option to control which block the link element will be appended to. By default it will append to the css block.

If key ‘rel’ in $options array is set to ‘import’ the stylesheet will be imported.

This method of CSS inclusion assumes that the CSS file specified resides inside the webroot/css directory if path doesn’t start with a ‘/’.

echo $this->Html->css('forms');

Will output:

<link rel="stylesheet" href="/css/forms.css" />

The first parameter can be an array to include multiple files.

echo $this->Html->css(['forms', 'tables', 'menu']);

Will output:

<link rel="stylesheet" href="/css/forms.css" />
<link rel="stylesheet" href="/css/tables.css" />
<link rel="stylesheet" href="/css/menu.css" />

You can include CSS files from any loaded plugin using plugin syntax. To include plugins/DebugKit/webroot/css/toolbar.css you could use the following:

echo $this->Html->css('DebugKit.toolbar.css');

If you want to include a CSS file which shares a name with a loaded plugin you can do the following. For example if you had a Blog plugin, and also wanted to include webroot/css/Blog.common.css, you would:

echo $this->Html->css('Blog.common.css', ['plugin' => false]);

Creating CSS Programatically¶

Cake\View\Helper\HtmlHelper::style(array $data, boolean $oneline = true)¶

Builds CSS style definitions based on the keys and values of the array passed to the method. Especially handy if your CSS file is dynamic.

echo $this->Html->style([
    'background' => '#633',
    'border-bottom' => '1px solid #000',
    'padding' => '10px'
]);

Will output:

background:#633; border-bottom:1px solid #000; padding:10px;

Creating meta Tags¶

Cake\View\Helper\HtmlHelper::meta(string|array $type, string $url = null, array $options = [])¶

This method is handy for linking to external resources like RSS/Atom feeds and favicons. Like css(), you can specify whether or not you’d like this tag to appear inline or appended to the meta block by setting the ‘block’ key in the $attributes parameter to true, ie - ['block' => true].

If you set the “type” attribute using the $attributes parameter, CakePHP contains a few shortcuts:

<?= $this->Html->meta(
    'favicon.ico',
    '/favicon.ico',
    ['type' => 'icon']
);
?>
// Output (line breaks added)
// Note: The helper code makes two meta tags to  ensure the
// icon is downloaded by both newer and older browsers
// which require different rel attribute values.
<link
    href="/subdir/favicon.ico"
    type="image/x-icon"
    rel="icon"
/>
<link
    href="/subdir/favicon.ico"
    type="image/x-icon"
    rel="shortcut icon"
/>

<?= $this->Html->meta(
    'Comments',
    '/comments/index.rss',
    ['type' => 'rss']
);
?>
// Output (line breaks added)
<link
    href="http://example.com/comments/index.rss"
    title="Comments"
    type="application/rss+xml"
    rel="alternate"
/>

This method can also be used to add the meta keywords and descriptions. Example:

<?= $this->Html->meta(
    'keywords',
    'enter any meta keyword here'
);
?>
// Output
<meta name="keywords" content="enter any meta keyword here" />

<?= $this->Html->meta(
    'description',
    'enter any meta description here'
);
?>
// Output
<meta name="description" content="enter any meta description here" />

In addition to making predefined meta tags, you can create link elements:

<?= $this->Html->meta([
    'link' => 'http://example.com/manifest',
    'rel' => 'manifest'
]);
?>
// Output
<link href="http://example.com/manifest" rel="manifest"/>

Any attributes provided to meta() when called this way will be added to the generated link tag.

Creating DOCTYPE¶

Cake\View\Helper\HtmlHelper::docType(string $type = 'html5')¶

Returns a (X)HTML DOCTYPE (document type declaration). Supply the document type according to the following table:

echo $this->Html->docType();
// Outputs: <!DOCTYPE html>

echo $this->Html->docType('html4-trans');
// Outputs:
// <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
//    "http://www.w3.org/TR/html4/loose.dtd">

Linking to Images¶

Cake\View\Helper\HtmlHelper::image(string $path, array $options = [])¶

Creates a formatted image tag. The path supplied should be relative to webroot/img/.

echo $this->Html->image('cake_logo.png', ['alt' => 'CakePHP']);

Will output:

<img src="/img/cake_logo.png" alt="CakePHP" />

To create an image link specify the link destination using the url option in $attributes.

echo $this->Html->image("recipes/6.jpg", [
    "alt" => "Brownies",
    'url' => ['controller' => 'Recipes', 'action' => 'view', 6]
]);

Will output:

<a href="/recipes/view/6">
    <img src="/img/recipes/6.jpg" alt="Brownies" />
</a>

If you are creating images in emails, or want absolute paths to images you can use the fullBase option:

echo $this->Html->image("logo.png", ['fullBase' => true]);

Will output:

<img src="http://example.com/img/logo.jpg" alt="" />

You can include image files from any loaded plugin using plugin syntax. To include plugins/DebugKit/webroot/img/icon.png You could use the following:

echo $this->Html->image('DebugKit.icon.png');

If you want to include an image file which shares a name with a loaded plugin you can do the following. For example if you had a Blog plugin, and also wanted to include webroot/img/Blog.icon.png, you would:

echo $this->Html->image('Blog.icon.png', ['plugin' => false]);

If you would like the prefix of the URL to not be /img, you can override this setting by specifying the prefix in the $options array

echo $this->Html->image("logo.png", ['pathPrefix' => '']);

Will output:

<img src="logo.jpg" alt="" />

Creating Links¶

Cake\View\Helper\HtmlHelper::link(string $title, mixed $url = null, array $options = [])¶

General purpose method for creating HTML links. Use $options to specify attributes for the element and whether or not the $title should be escaped.

echo $this->Html->link(
    'Enter',
    '/pages/home',
    ['class' => 'button', 'target' => '_blank']
);

Will output:

<a href="/pages/home" class="button" target="_blank">Enter</a>

Use '_full'=>true option for absolute URLs:

echo $this->Html->link(
    'Dashboard',
    ['controller' => 'Dashboards', 'action' => 'index', '_full' => true]
);

Will output:

<a href="http://www.yourdomain.com/dashboards/index">Dashboard</a>

Specify confirm key in options to display a JavaScript confirm() dialog:

echo $this->Html->link(
    'Delete',
    ['controller' => 'Recipes', 'action' => 'delete', 6],
    ['confirm' => 'Are you sure you wish to delete this recipe?']
);

Will output:

<a href="/recipes/delete/6"
    onclick="return confirm(
        'Are you sure you wish to delete this recipe?'
    );">
    Delete
</a>

Query strings can also be created with link().

echo $this->Html->link('View image', [
    'controller' => 'Images',
    'action' => 'view',
    1,
    '?' => ['height' => 400, 'width' => 500]
]);

Will output:

<a href="/images/view/1?height=400&width=500">View image</a>

HTML special characters in $title will be converted to HTML entities. To disable this conversion, set the escape option to false in the $options array.

echo $this->Html->link(
    $this->Html->image("recipes/6.jpg", ["alt" => "Brownies"]),
    "recipes/view/6",
    ['escape' => false]
);

Will output:

<a href="/recipes/view/6">
    <img src="/img/recipes/6.jpg" alt="Brownies" />
</a>

Setting escape to false will also disable escaping of attributes of the link. You can use the option escapeTitle to disable just escaping of title and not the attributes.

echo $this->Html->link(
    $this->Html->image('recipes/6.jpg', ['alt' => 'Brownies']),
    'recipes/view/6',
    ['escapeTitle' => false, 'title' => 'hi "howdy"']
);

Will output:

<a href="/recipes/view/6" title="hi &quot;howdy&quot;">
    <img src="/img/recipes/6.jpg" alt="Brownies" />
</a>

Also check Cake\View\Helper\UrlHelper::build() method for more examples of different types of URLs.

Linking to Videos and Audio Files¶

Cake\View\Helper\HtmlHelper::media(string|array $path, array $options)¶

Options:

• type Type of media element to generate, valid values are “audio” or “video”. If type is not provided media type is guessed based on file’s mime type.

• text Text to include inside the video tag

• pathPrefix Path prefix to use for relative URLs, defaults to ‘files/’

• fullBase If provided the src attribute will get a full address including domain name

Returns a formatted audio/video tag:

 <?= $this->Html->media('audio.mp3') ?>

 // Output
 <audio src="/files/audio.mp3"></audio>

 <?= $this->Html->media('video.mp4', [
     'fullBase' => true,
     'text' => 'Fallback text'
 ]) ?>

 // Output
 <video src="http://www.somehost.com/files/video.mp4">Fallback text</video>

<?= $this->Html->media(
     ['video.mp4', ['src' => 'video.ogg', 'type' => "video/ogg; codecs='theora, vorbis'"]],
     ['autoplay']
 ) ?>

 // Output
 <video autoplay="autoplay">
     <source src="/files/video.mp4" type="video/mp4"/>
     <source src="/files/video.ogg" type="video/ogg;
         codecs='theora, vorbis'"/>
 </video>

Linking to Javascript Files¶

Cake\View\Helper\HtmlHelper::script(mixed $url, mixed $options)¶

Include a script file(s), contained either locally or as a remote URL.

By default, script tags are added to the document inline. If you override this by setting $options['block'] to true, the script tags will instead be added to the script block which you can print elsewhere in the document. If you wish to override which block name is used, you can do so by setting $options['block'].

$options['once'] controls whether or not you want to include this script once per request or more than once. This defaults to true.

You can use $options to set additional properties to the generated script tag. If an array of script tags is used, the attributes will be applied to all of the generated script tags.

This method of JavaScript file inclusion assumes that the JavaScript file specified resides inside the webroot/js directory:

echo $this->Html->script('scripts');

Will output:

<script src="/js/scripts.js"></script>

You can link to files with absolute paths as well to link files that are not in webroot/js:

echo $this->Html->script('/otherdir/script_file');

You can also link to a remote URL:

echo $this->Html->script('http://code.jquery.com/jquery.min.js');

Will output:

<script src="http://code.jquery.com/jquery.min.js"></script>

The first parameter can be an array to include multiple files.

echo $this->Html->script(['jquery', 'wysiwyg', 'scripts']);

Will output:

<script src="/js/jquery.js"></script>
<script src="/js/wysiwyg.js"></script>
<script src="/js/scripts.js"></script>

You can append the script tag to a specific block using the block option:

echo $this->Html->script('wysiwyg', ['block' => 'scriptBottom']);

In your layout you can output all the script tags added to ‘scriptBottom’:

echo $this->fetch('scriptBottom');

You can include script files from any loaded plugin using plugin syntax. To include plugins/DebugKit/webroot/js/toolbar.js You could use the following:

echo $this->Html->script('DebugKit.toolbar.js');

If you want to include a script file which shares a name with a loaded plugin you can do the following. For example if you had a Blog plugin, and also wanted to include webroot/js/Blog.plugins.js, you would:

echo $this->Html->script('Blog.plugins.js', ['plugin' => false]);

Creating Inline Javascript Blocks¶

Cake\View\Helper\HtmlHelper::scriptBlock($code, $options = [])¶

To generate Javascript blocks from PHP view code, you can use one of the script block methods. Scripts can either be output in place, or buffered into a block:

// Define a script block all at once, with the defer attribute.
$this->Html->scriptBlock('alert("hi")', ['defer' => true]);

// Buffer a script block to be output later.
$this->Html->scriptBlock('alert("hi")', ['block' => true]);

Cake\View\Helper\HtmlHelper::scriptStart($options = [])¶

Cake\View\Helper\HtmlHelper::scriptEnd()¶

You can use the scriptStart() method to create a capturing block that will output into a <script> tag. Captured script snippets can be output inline, or buffered into a block:

// Append into the 'script' block.
$this->Html->scriptStart(['block' => true]);
echo "alert('I am in the JavaScript');";
$this->Html->scriptEnd();

Once you have buffered javascript, you can output it as you would any other View Block:

// In your layout
echo $this->fetch('script');

Creating Nested Lists¶

Cake\View\Helper\HtmlHelper::nestedList(array $list, array $options = [], array $itemOptions = [])¶

Build a nested list (UL/OL) out of an associative array:

$list = [
    'Languages' => [
        'English' => [
            'American',
            'Canadian',
            'British',
        ],
        'Spanish',
        'German',
    ]
];
echo $this->Html->nestedList($list);

Output:

// Output (minus the whitespace)
<ul>
    <li>Languages
        <ul>
            <li>English
                <ul>
                    <li>American</li>
                    <li>Canadian</li>
                    <li>British</li>
                </ul>
            </li>
            <li>Spanish</li>
            <li>German</li>
        </ul>
    </li>
</ul>

Creating Table Headings¶

Cake\View\Helper\HtmlHelper::tableHeaders(array $names, array $trOptions = null, array $thOptions = null)¶

Creates a row of table header cells to be placed inside of <table> tags.

echo $this->Html->tableHeaders(['Date', 'Title', 'Active']);

Output:

<tr>
    <th>Date</th>
    <th>Title</th>
    <th>Active</th>
</tr>

echo $this->Html->tableHeaders(
    ['Date', 'Title','Active'],
    ['class' => 'status'],
    ['class' => 'product_table']
);

Output:

<tr class="status">
     <th class="product_table">Date</th>
     <th class="product_table">Title</th>
     <th class="product_table">Active</th>
</tr>

You can set attributes per column, these are used instead of the defaults provided in the $thOptions:

echo $this->Html->tableHeaders([
    'id',
    ['Name' => ['class' => 'highlight']],
    ['Date' => ['class' => 'sortable']]
]);

Output:

<tr>
    <th>id</th>
    <th class="highlight">Name</th>
    <th class="sortable">Date</th>
</tr>

Creating Table Cells¶

Cake\View\Helper\HtmlHelper::tableCells(array $data, array $oddTrOptions = null, array $evenTrOptions = null, $useCount = false, $continueOddEven = true)¶

Creates table cells, in rows, assigning <tr> attributes differently for odd- and even-numbered rows. Wrap a single table cell within an [] for specific <td>-attributes.

echo $this->Html->tableCells([
    ['Jul 7th, 2007', 'Best Brownies', 'Yes'],
    ['Jun 21st, 2007', 'Smart Cookies', 'Yes'],
    ['Aug 1st, 2006', 'Anti-Java Cake', 'No'],
]);

Output:

<tr><td>Jul 7th, 2007</td><td>Best Brownies</td><td>Yes</td></tr>
<tr><td>Jun 21st, 2007</td><td>Smart Cookies</td><td>Yes</td></tr>
<tr><td>Aug 1st, 2006</td><td>Anti-Java Cake</td><td>No</td></tr>

echo $this->Html->tableCells([
    ['Jul 7th, 2007', ['Best Brownies', ['class' => 'highlight']] , 'Yes'],
    ['Jun 21st, 2007', 'Smart Cookies', 'Yes'],
    ['Aug 1st, 2006', 'Anti-Java Cake', ['No', ['id' => 'special']]],
]);

Output:

<tr>
    <td>
        Jul 7th, 2007
    </td>
    <td class="highlight">
        Best Brownies
    </td>
    <td>
        Yes
    </td>
</tr>
<tr>
    <td>
        Jun 21st, 2007
    </td>
    <td>
        Smart Cookies
    </td>
    <td>
        Yes
    </td>
</tr>
<tr>
    <td>
        Aug 1st, 2006
    </td>
    <td>
        Anti-Java Cake
    </td>
    <td id="special">
        No
    </td>
</tr>

echo $this->Html->tableCells(
    [
        ['Red', 'Apple'],
        ['Orange', 'Orange'],
        ['Yellow', 'Banana'],
    ],
    ['class' => 'darker']
);

Output:

<tr class="darker"><td>Red</td><td>Apple</td></tr>
<tr><td>Orange</td><td>Orange</td></tr>
<tr class="darker"><td>Yellow</td><td>Banana</td></tr>
